My Younger Brother Paved my Flower Path

When I was reincarnated, I only wanted to live happily with my one and only younger brother. But the problem is, my younger brother, who will do anything for my sake, gave me the crown off the head of the tyrant who was the Emperor just up until yesterday.

"I'll make the continent kneel at your feet, Sister!"

...At this rate, before becoming the first Empress to unify the continent, I might die from overwork. And so, I decided to bring in a pushover--I mean, a husband--who is good at doing work, but...

The Duke of Derhardt is called the monster of the North. He's compatible with his brother-in-law and is the Crazy-Bastard-No-2 who also dreams of unification.

Ha... these punks really....
